I ended up having to pull the head off my 400ex and was wondering what the torque specs are for the head bolts, and what order do you torque them in. I don't want to buy the clymers if I don't have to and I have built quite a few different motors. Thanks!

Right on helmut thank you very much! And the google thing I would go there but is the info trustworthy enough for a very precise and needed answer. I know where to go and who I can trust on here. Helmut always has the answers lol. But thanks fellas either way!

You're welcome. Yeah, I got the info from the service manual, so it should be accurate.

You only need two tools in life -- WD-40 and duct tape. If it doesn't move and should, use the WD-40. If it shouldn't move and does, use the duct tape.

Awesome good info thanks! I ordered a namura topend gasket kit so its gunna have a new head gasket. do you have to put anything on the head gasket? It looks like there was some sort of sealer on it when I pulled it off. And i am certain I'm the first one pulling this motor apart so it wasn't something someone did.
